What are this polygons counter on the main page? what it resembles? (CLOSED) (CLOSED)

they are increasing every second

When 3D models are uploaded, the vendor provides the polygon count for that model, and that number is provided for customers on the product page. 
RenderHub keeps a record of all of that, and displays the total poly count for all models uploaded, in a fun way with that counter. 
You see it constantly changing because as new models are uploaded, the counter is "catching up" to the new total. 

I hope that makes sense, and I'm sorry nobody has responded to you earlier. 

ok Thanks. This website is kinda new. seems like empty all the time

No problem, and you're right... RenderHub IS "kinda new" - but there have been a bunch of cool things happening here lately. Lots of new vendors, and tons of new content. 
If you know of any vendors looking for a new marketplace to sell their products, please spread the word. That would be greatly appreciated, and would benefit everyone. 

And I'm not sure if you've seen the new Product Showcase section of the forums. Feel free to post there to feature your own products, and get some more eyes on your stuff.
